Which fixative is used for bloody bone marrow aspirates?

When fixing bone marrow aspirates, preserving the delicate hematopoietic cells and their cytoplasmic detail is essential for accurate morphology and staining. Helly's fixative, a form of formalin-based solution containing picric acid, rapidly preserves cells and maintains both nuclear and cytoplasmic integrity, making marrow smears and blood-rich specimens look true to life under the microscope. Other fixatives in the mix tend to be harsher or cause more distortion in such samples, so Helly's is the preferred choice for bloody bone marrow aspirates.
